Hybrid tea rose plant named ‘Panamaril’

ABSTRACT

A new variety of hybrid tea rose plant producing yellow flowers of good form.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distant variety of rose plantof the hybrid tea rose class which was created by crossingundistributed, unnamed and unpatented seedlings as seed and pollenparents in The Netherlands. The varietal denomination of the new varietyis ‘Panamaril’.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety whichdistinguish it from its parent and all other varieties of which I amaware are its attractive yellow flowers.

Asexual reproduction by budding of the new variety as performed in TheNetherlands shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations. The new variety has been reproducedthrough propagation by cuttings, grafting, budding and micropropagation.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying two illustrations show typical specimens of thevegetative growth and flowers of the new variety in different stages ofdevelopment, and as a cut flower, depicted in color as nearly true as itis reasonably possible to make the same in a color illustration of thischaracter.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of 9-month old plants of the newvariety, with color terminology in accordance with The RoyalHorticultural Society Colour Chart (R.H.S.C.C.) and horticulturalterminology in accordance with standard terminology used inUPOV-approved horticultural guideline. The terminology used in colordescriptions herein refers to plate numbers in the aforementioned colorchart. Phenotypic expression may vary depending upon growing conditionsunder different climate, soil, and cultivation conditions.

Parentage: Seed and pollen parents are seedlings.

Class: Hybrid Tea.

As can be seen in the accompanying detail illustration there is shown anew shoot, 1; compound three, five and seven leaflet leaves, 2, 3 and 4,respectively; a stem, 5; buds, 6 and 7; a flower, 8, about one-thirdopen to one-half open and a flower, 9, more fully open. Also shown areflower stems 10, 11 and 12, with reproductive organs displayed.

COMPARISON WITH PARENTS

The female parent produces yellow roses, and the male parent producesyellow ochre flowers.

The following further horticultural description is based on observationsmade of specimens grown under glass in The Netherlands.
